From Man to Woman and Back Again, Tiresias, Fulgentius, Myth. II.8

Tiresias serpentes duos concumbentes vidit, quos cum virga percussisset, in feminam conversus est. Iterum post temporis seriem eos concumbentes vidit, similiterque percussis iterum est in pristinam naturam conversus.

--Fulgentius, Myth. II.8

When Tiresias saw two snakes mating, he struck them with a stick and was turned into a woman. After a while, he saw them mating again, and as soon as he struck them again he returned to his original body (in pristinam naturam).
